你换一下位置就更好理解了.
The Everglades that （或which）is home to numerous species of plants and wildlife,is a watery plain covered with saw grass.
定语从句和同位语从句最简单的区别：
就是看引导词that引导定语从句时,在从句中一般作主语或宾语(指物时还可以用which代替),并且作宾语时常常省略?that在同位语从句中仅起连接作用,不充当任何成分,并且不能省略,也不能用which来代替
The order that we should send a few people to help the other groups was received yesterday.我们应派几个人去帮别的几个小组的命令昨天收到了(同位语从句,是对order的具体解释,that虽不作成分,但不能省略)
汉语解释就不用了,别人都说的挺好的～
不懂的话继续问
